SPECIFICATION oming part of Letters PatentNo. 360,185, dated March 29.1887,

Application filed August 3l, 1585. Serial No. 175,857. (No model.)

To @ZZ whom it may concern:

Beitknown that we, FAIRFAX HVHEELAN and ALBERT SeHURcH, both of the cityand county of San Francisco, State of California,

5 have invented an Improvement in Chromatic- Printing Apparatus; and wehereby declare the following to be a full, clear, and exact descriptionof thesanie.

Our invention relates to certain improve- 1o ments in chromaticprinting, so that two or more colors may be printed at one impression.

It consists in the construction and combination of devices, all of whichwe shall hereinafter fully describe.

The object of our invention is to provide a practical apparatus forprintingin two or more colors.

Referring to the accompanying drawings,

zo Figure l is a longitudinal vertical section of a portion ot' ourapparatus, showing` a part of the impression-roller', thedistributing-rollers, and inking-pad for one set of type or surfaces,the other set of type or surfaces, its inkingroller, and means foroperating` it. Fig. 2 is a plan view of the iuking apparatus for thetype-surface D, showing the frames M and WV,

in section. Fig. 3 is a plan view ofthe mechanism illustrated'in Fig. l,and showing portions of the frames M and NV broken away. Fig. 4t is adetail showing the frames M I? NV and connections.

A is the impression-roller of a printingpress.

B B are rollers which are used for distributing and applying any colorof ink to a fixed set of type, B', which are the usual typeof theordinary form.

C is the ink-distributing table,whieh reciprocates in order toreceiveink from the inkingroller (not here shown) and to carry it to thedistributing-rollers B.

D represents the type or surfaces which are to print the second color,the type which print the primary color being the ordinary typeheretofore mentioned. The type D are fixed in the reciprocating bed andmove with it.

It is necessary that the type D should be inked before passing under theimpression- 5o roller, and should be moved out of the way while passingbeneath the rollers B of the first set of type, and again raised toplace after passing these rollers, so as to present theirsurfaces to theimpression-roller.

In Fig. l is shown the bed or block X for the type D,which are on aframe, X, having corrugated under surface, or furnished with alternateelevations and depressions, as shown at E, and these move over similarelevations or depressions,F,on a plate, Xi", in the base or 6o bed X.Vhen the elevations E and F are brought in vertical line, the elevationsE, resting on top of those at F, will raise the type-surface so that itis possible to receive ink or give an impression; but when theelevations E fall into the depressions between F the type will bedepressed below the level of the inking-rollers. In order toproduce thisalternate elevation and depression of the type,the plate X3 of theelevationsF is so mounted in the bed 7o X as to be reciprocated slightlytherein, and said frame is connected bya rod, G, toa crankpin, g, on adrum or cylinder, H, mounted in one end of the bed, so that when saidcylinder is oscillated it will canse the frame of the 7g elevations F tobe reciprocated, thus raising or lowering the type D, as heretoforedescribed.

In order to move the elevations F at the proper time, the pins I arefixed in the end of 8o the drum H, and these pins, as they move againstsuitable arms or lugs placed at proper points, will be struck and causethe drum H to oscillate for the purpose described. But before the type Dare depressed they should be inked. rlhis is accomplished asv follows:To the side of a fixed main frame, M, is secured a frame, XV, which isprovided with small anti-friction rollers w, n'tted in a vertical slotAin said frame M. Fis another frame, which go is slotted and travelsvertically on small roll` ersp, secured to frame 'V. Journaled on ashaft, q, passing through the frame l is the inking-roller Q. Iivoted tothe frame Wis a bell-crank lever, L, the lower end of which carries aroller, N. The upper end of the lever L cornes in contact with the lowerarm of a pivoted bell-crank lever, O, the pivot-shaft of which passesthrough the frames NV and M, and said lever is influenced to remain inposiloo tion by means of aspring, o. The other or horizontal arm of thelever O is pivoted to the frame P at o. The lever L is limited in itsmovement by the fixed stop Z.

The operation so far as explained is as follows The type-bed X has onits side a track, v

As'the type D pass forward this track tact with the type D. To theframe'W is secured the arm J, which comes in contact with the pin Iofthe drum H, whereby it causes a partial rotationof said drum, so thatthrough the pitman G the elevations F are moved to allow the projectionsE of the type-frame X3 to fall into the intervening depressions,so thatthe surface of said type is depressed in order to avoid thedistributing-rollers B. It is also necessary that the inking-pad Gshould avoid the inking-roller Q. Accordingly we have the followingmechanism z Jourualed in the end of a bell-crank lever, S, is a largewheel, R, having a cushioned surface, r. The lever S is pivoted on ashaft, T, to the main frame M, andv is connected by a link, II, with abellcrank lever, V, pivoted on a shaft, X2, which passes through themain frame M. The other arm of the lever V is pivoted to the frame W.The lever Sis held in its position by means of a pivoted arm, s',influenced by a spring, s2, and connected with the lever S by a link, s.As the inking-pad C moves forward it first comes in Contact with thecushioned wheel R and raises said wheel, whereby, through the levers Sand V and the link U,the Whole frame Wis raised slightly, and as saidframe carries the frame P, in which the inkiug-roller Q is mounted, itwill be seen that said roller is thus raised above the inking-pad,so'that it does not come in contact with said pad. As the arm J issecured to the vertically-adjustable frame W it will rise as it comes incontact with the track d on the type-bed X, and will therefore notinterfere with the passage of said bed.

When the type D, depressed, as heretofore described, to avoid .thedistributing-rolls B, have passed said rolls and 'are'l about to passunder the impression-cylinder A, it is necessary that said type shall beraised again to position. This is accomplished by the arm X, which, asin the case of the arm J, comes in contact with the uppermost of thepins I of the drum H inthe bed of type D. Thus just before the type Dpass under the cylinder they are elevated tol position, and consequentlymake their impression. But it is also necessary that the arm K shall notbe in the Way of the inking-table C. To avoid this We secure the arm Kto one end of a series of levers, Y, pivoted to one another, andcarrying a roller, Z, with which the table G comes in contact and raisesit, whereby the arm K is also raised out of the way.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a chromatic-printing press in which two or more colors areemployed, a means comprising an oscillatory drum and aVrecprocating-.plate operated thereby for depressing one set oftype-surfaces below the level of the remaining type, so that the lattermay be inked independently of the former, substantially as hereindescribed.

2. Ina chromatic-printing apparatus, the type-surface D, adapted to bedepressed or raised, in combination with a drum upon the type-bed andlugs or projections which engage pins upon the drum, so as to partiallyrotate it, and through it cause the type to be depressed or to beelevated, substantially as herein described.

3. In a chromatic-printing apparatus, the reciprocating type-bed X,having type-surfaces D, which may be raised or depressed, as described,in combination with an inking. roller and a mechanism comprising theframe P and suitable levers operated by the reciprocating type-bed todepress said rollerso as to distribute ink upon the face of the typewhen passing beneath it, substantially as herein described.

4. In a chromatic-printing apparatus, a reciprocating form carrying typewhich may be be elevated or depressed, and a second set of xed typeinked by suitable distributing-rollers, in combination with aframecarrying the inking-roller of the, first set of type land amechanism by which it may be raised bythe passage of theink-distributing table, so as to be out of contact with it,substantially as herein described. j

5. In a chromatic -printing apparatus in Which two or more colors areemployed, a reciprocating bed carrying one set of type which may beelevated to and depressed below the level of a second set, a second setof type, and an ink-table, also carried by said b ed, a frame carryingan inking-roller for the first set of type,

ICO

IIC

and mechanism, substantially as described,

- engaged by said bed in its passage, for depressing said roller intocontact with the type,

In witness whereof We have hereunto set our hands.
